I'm having trouble with a circuit I'm putting together. I think this is how to represent it (may be wrong about that).
I'm using a SPDT switch to turn off a circuit, but I want it to turn off after a delay. I have a 12v Delay Switch Ne555 Module that I switch on when MAG is in an NC state. This works.
The issue is the circuit is permanently on and never switches off. It seems like the timer fires immediately but never switches. The module makes a buzzing noise.
If I move the timer switch to the opposite leg the timer works - it turns off immediately and then turns on after a delay - the opposite of what I want. No noise is made.
I think the diagram is slightly wrong - there isn't two switches inside the module. I just wasn't sure how to represent a timer switch that needed voltage.
What am I doing wrong?
